SUPPORTING- -CLIP FOR BRAKE-ARMS OF BICYCLES.

SPECIFICATION forming part of Letters Patent No. 534,846, dated February26, 1895.

Application filed June 15, 1894.. Serial No. 514,706. (lilo model.)

To 00% whom it may concern.-

Be it known that I, FREDERICK J. STIMSON, a citizen of the UnitedStates, and a resident of the city of New York and State of New York,have invented a certain new and useful Improvement in Supporting-Clipsfor Brake- Arms of Bicycles; and I do hereby declare the following to'bea full, clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification. 7

My invention has relation to a certain new and useful improvement inclips or attachments to bicycle brakes, and substantially consists inthe construction hereinafter particularly described and claimed.

The object of my invention is to provide a construction of clip uponwhich the pivoted brake arm may be secured to the bicycle withoutliability of becoming pinched or bound by the clip while at the sametime the clip may be most rigidly secured to the handlebar or frameworkof the bicycle.

In the accompanying drawings, Figure 1 is a perspective view of a clipdetached with a section of the brake bar indicated in position in dottedlines. Fig. 2 is a longitudinal sectional view of the clip, and Fig. 3represents the clip in position upon the handle-bar supporting thebrake-arm.

The clip is composed of two main sections,

A, A, each of substantially similar construction placed opposite eachother invertedly as shown in the accompanying drawings. Each of thecastings, A, A, is provided with an upper arm, a, curved preferably inthe arc of a circle to fit over the rounded handle-bar, and a lowerdepending arm, 0/, preferably recessed, the construction being such thatwhen in position the upper arms, a, form around and bind upon thehandle-bar of the bicycle, while the construction of the lower arms, a,provides a recess between them for the reception of the main brake arm,I), the width of the recess, when the two parts are secured in positionupon the handle-bar, being preferably slightly greater than the width ofthe brake arm.

As a means of securing the clip upon the handle-bar a keyedscrew-threaded bolt, or

thumbscrew, D, is screwed into one of the castings, as A, and carriesthe other casting, A, loosely upon it through the medium of the collar,d. In this manner the clip may be readily adjusted upon the handle-bar,or other parts, of varying diameters, or sizes, and the clip will berigidly and immovably secured by the tightening of the bolt, D. In orderto prevent the lower arms, a, from impinging and binding upon the sidesof the brake arm, I), when pivoted in position between them, I providethrough the brake arm a distanceregulating pivot, E, horizontallyadjustable in and between the said arms, a, to the end that the arms maybe positively separated by proper adjustment of the pivot, E, andprevented from impinging, as when the adjustment of the upper arms, a,upon the handle bar would tend under certain conditions to have thateffect.

The distance-regulating pivot, E, is adjusted in a screw-threadedorifice in one of the downwardly projecting arms, Cb, as the arm of thesection, A, while the opposite end is adapted to bear in a recess ordepression, 0, provided in the other downwardly projecting arm, whichrecess also forms a bearing for the outer end of the pivot, E, which issubjected to more or less strain in the operation of the brake-arm. Inthis construction the downwardly projecting arms, a, supporting andinclosing the brake-arm may be maintained at any desired distance apartto prevent the brake-arm from binding, as when the clip is rigidlysecured to the handle-bar, which thus allows at all times a free andeasy movement of the brake-arm. Further it is clear from theconstruction that the operation of the brake-arm cannot tend to loosenthe securing bolt, D; and also that the outward strain upon the arms, a,occasioned by the bolt, E, tends not only to separate the arms, a, butalso to assist in locking the bolt, D, in the combined sections.

I am aware that numerous other constructions of supporting clips forbrake arms, and for other parts, have hereto fore been invented, and donot claim the same broadly, my invention residingmainly in theconstruction of device herein particularly claimed.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A securing clip consisting of two independent sections each havingupper inwardly protruding recessed gripping jaws, a transverselydisposed screw-threaded bolt provided through said sections, dependingperpendicularl y disposed arms parallel with each other at a distancefrom each other forming a recess between said depending arms andadjustable threaded pivot transversely disposed through one of said armsand through said recess having its inner end impinging against theopposite depending arm for regulating the distance between said arms andfor carrying the brake-arm, substantially as described.

2. A securing clip consisting of the sections, A, A, gripping arms orjaws, a, downwardly projecting arms, a, transversely disposed securingbolt, D, having threads upon its outer end engaging with ascrew-threaded orifice in one of said sections, as A, and protrudingthrough the inner section for securing the clip to the frame of themachine, and screwthreaded distance regulating pivot, E, carried in oneof the arms, a and impinging against the opposite arm for spacing saidarms, substantially as described.

3. A securing clip consisting of the sections, A, A, oppositely disposedgripping arms, a, downwardly projecting arms, a, perpendicularlydisposed at a distance from each other forming an intervening recess,transversely disposed screw-threaded securing bolt, D, provided in ascrew-threaded orifice in the section, A, loosely carrying the innersection, A, and collar, d, provided upon said bolt, D,impinging againstthe outer surface of the section, A, transversely disposeddistance-regulating pivot, E, screw-threaded at or near its outer endand provided in a screw-threaded orifice in the section, A, and recess,0, provided in the arm, a, of the section, A, for the reception of theinner end of the pivot, E, substantially as described.

In witness whereof I have hereunto set my hand this-12th day of June, A.D. 1894.
